HELP! Redline

HELP! Redline
I'm having a tough time deciding on a specific redline gear oil. I have a B-series tranny with a Spoon LSD(Clutch type). I am getting really serious notchy shifts into any gear. I have to jam it into 1st at times.
I just got off the phone with a Redline distributor and he has explained to me in detail on gearoils by Redline. It seems that all GL-5 oils will cause your shifter to be notchy but is ideal for clutch type LSDs by prolonging the LSDs lifespan and dampering chattering noises. Other than causing a notchy feel, it also damages your syncros over time due to friction modifiers in GL-5 gearoils which has a high sulphur content. Redline has a large variant of gearoils. The Redline MTL being the most suited for stock Honda gearboxes even for those with helical LSDs. But for clutch type LSDs, it seems the syncros are put at risk. According to the distributor, he says that the Redline Shockproof series of oil is suppose to give a balance between syncro and LSD protection. Should I get that even though its stated on http://www.redlineoil.com that it has a 75w90 rating?
Can anyone help me here and advise me which Redline gearoil to get? I am perfectly okay with the chatters, but I do not want to kill my syncros and LSDs. Would like to hear other recommendations but at the moment I would jstu want to focus on Redline.

I used the redline lightweight shockproof for about 30,000 miles and it was a great gear oil for me. Felt great in the summer time, but it is thick. In the winter it was notchy until the car warmed up. However, I have gone back to OEM now and I'm still grindless with 100,000 miles on the original transmission.

Re: (P1_Variable)
I havent had any problems with the Penzoil GL5 I'm using.... Maybe its time for a rebuild or atleast a synchro replacement....

So should I just use Redline's 75w90 oil and disregard the shortened syncro life and live with a slightly notchy shift feel compared to using Redline MTL which will guarantee crisp shifting and protected syncros but bad LSD protection?
Seems like the former has 1 con compared to 2 cons in the latter.

It sounds like you're worried because of the viscosity numbers being so high. There's no need to be worried. Gear oil is rated using a different scale from motor oil.
Redline MTL is rated at 70W80 gear oil viscosity. That is roughly the same viscosity as motor oil that is rated between 5W30 and 10W30. Redline also makes MT-90 fluid, rated at 75W90, which is similar in viscosity to 10W40 motor oil.
I do not know anything about whether this particular oil will be appropriate for your application or not; I am only commenting about the viscosity itself.

EDIT: Corrected viscosity information.

Do you have something that states that as truth? Not doubting you at all, usually you have a book behind you when it comes to tires, just wondering if you have something about this.....

Re: HELP! Redline (walker111)
Found this Note that 75W-80 GEAR oil is equivalent to
10W30 MOTOR oil,
From here:
http://www.faqs.org/faqs/autos/vw/performance-faq/
And
Noting that "50" weight engine is equivalent viscosity to "90" weight gear, but the motor oil lacks the extreme pressure additives found in the gear oil

I stated the figures above slightly wrong. I thought the original reference to 75W90 was about Redline MTL, when a closer reading shows it was about their shockproof fluid. I apologize for the misstatement, and have corrected it in my previous post.
Redline MTL is rated at 70W80 gear oil viscosity, which is in between 5W30 and 10W30 engine oil in viscosity. As noted on Redline's website, "This 70W80 GL-4 Gear Oil (SAE 5W30/10W30 engine oil viscosity) is designed for use in manual transmissions and transaxles." Redline also makes MT-90 gear oil, rated at 75W90, which is closer to 10W40 motor oil in viscosity.
