Hi, I'm thinking of buying the Lew's Mach 2 but aren't sure if its good for my type of situation.
The area where I fish in has a mossy bottom with a lot of lily pads. I use a frog mostly, which is 1/2 OZ. Sometimes I use a strike king swim jig 3/8 OZ.
Is the Lew's Mach 2 capable of handling 50# Braid with a 1/2 Oz frog?

Try out the Lew's Speed Spool LFS.

 

I'll agree with @swhit140

The LFS frame reels are stouter, the P2 pinion is a great durability upgrade in this reel, and Lou's mag brake doesn't add any mass to the spool.  

It also lets you change spool bearings, and not affect the drive, since the P2 drive bearing is separate from the spool/spindle.  

Looks better than my Super Duty G, which is my workhorse reel, and at lower cost.

I'd step up $10 and grab the Tournament MP. It's worth it to have the centrifugal brake + magnetic brake.. I fished with my buddy's the other night. It's a capable aluminum framed reel for bombing frogs and it includes the important P2 feature mentioned by @bulldog1935
