I just received my BB1 and Super Duty yesterday and have fished the T-pro, TS and MG for over a year.
The T-Pro is about light weight, carbon fiber handle and alloy gears. Great caster and smooth on the retrieve. Mine are all 6.4 to 1 ratio.
The TS is a bit heavier with alloy handle and brass gear set. The casting quality is right on parr with the T-Pro. Great workhorse reel. Probably the best overall value seeing it has dual cast control features.
The MG is not dual cast control and employs magnets only. I picked mine, a 5.1 and 7.1 to 1 ratio up at a sportsman show at a great price. They are a little more fickle to set but it only takes a half dozen casts. This is a good reel for pitching 3/16 oz and hevier baits. I would suggest the TS over this model however. For twenty bucks, it's worth having the dual cast control.
I have only test cast my BB1 at the local city lake. This reel is a caster ! I threw an Excalibur squarebill and darn near spooled the reel. This model is a 6 pin brake and no magnets. It clearly does not need magnets. I could probable fish all BB1's and cover every application. I really like this reel. It will oputcast my Gen 2 Revo Premiers and Winch's by a substrantial amount. This is a very smooth reel. Can't wait to flush and re-lube. It can only get better.
The Super Duty is designed for braid and has a little channel machined into the spool so line slip is no longer an issue. I wish this feature was on all the LEWS. I spooled mine up with 20# Sunline Sniper FC for pitchin this spring. It will replace one of my TS models so I can use it for chatterbaits/spinnerbaits. This model has the 95MM power handle. It is butter on the cast and retrieve. Over size Brass gears and dual cast control. I can't comment on the drag until I fish it for a while. The side plates have a soft touch rubberized coating. I plan on ito see how this material holds up before I consider getting another for punching with braid.
Hope this helps.
