I voted for the 50 mm, granted, you can't over carb because of going bigger, but the 50mm wil be snappier where you need it to launch that heavy beast. Respect to Dan for trying to not to upsell you. How many of these T/Bs has he sold? He probably knows something, maybe even had an unhappy customer or two.

 

52mm cause i don't tow according to Dan............
