Being MUCH taller than Opponent
I'm 6'5 and about ~185 lbs and ~10% bodyfat. (Haven't got any weird body proportions so my wingspan=height) I'm currently not training at a real gym but there's a general MMA club with some legit guys but mostly people who haven't done anything before.
I want to try competing in amateur MMA or Kickboxing after I get out of college so I'm trying to make sure I've got a good physical foundation in the 2 years I have left.
Thing bothering me is that most successful guys I see competing in the weight classes that I'd be able to make are around 5'10-6'2. Now that gives me a significant reach advantage but stockier guys seem to have a much easier time with grappling and have much more solid hooks/uppercuts. For example, I have a very hard time with guys muscling out of any sort of armlocks I do. Triangles and RNC are a huge majority of the submissions I land.
I'm wondering what the general opinion is on being much taller in MMA. Do the pros outweigh the cons? Or is it better to pack on some mass to compete at a higher weight to lessen the degree of the pros/cons?
TL;DR: Being ~5" taller than rest of prospective weight class, good or bad? Try and pack on 20-30lbs to jump up classes, or stay and use reach advantage?
Thanks in advance!
