Another great alternative to Synchromesh is BG Synchroshift. It's available in a petroleum/synthetic blended BG Synchroshift I, and a full-synthetic BG Synchroshift II.
Synthetic oils reduce friction more than Petroleum oils can. Keep in mind that your synchronizers actually need friction to work properly, so Honda MTF may work better. Using synthetic oils may make shifting MORE difficult despite the reduction in friction. That all depends on the materials used to manufature the synchros in any given transmission and some work better with it than others. Full-synthetic is better in a race car because the transmission usually spends more time at higher RPMs than a daily driver does. I have dual-synchros installed for my 1/2 shift, and my tranny is race-built, so I use BG II. Yes, it's a DSM, but just like a Honda, it's a soft aluminum-cased transmission with forged steel gearsets and bronze shaft bearings.
There are on-line vendors for BG products. Many speed shops like www.machv.com and www.roadraceengineering.com carry them. If you don't like the way your car shifts with synthetic gear oil, it's easy enough to drain it and re-fill it. It's a lot less expensive to use Honda MTF, though. I change my gear oils (tranny, transfer case, rear end) every 5k miles and it runs me about $80. I mix Redline ShockProof and BG II in a 50/50 for the xfer and rear. Thank goodness you don't have to deal with a 3.5qt capacity like I do.
