I seriously considered buying the Eddyline Merlin LT. I weigh 175
lbs. , 5'7" tall. The cockpit opening size wasn't a problem;
however, the volume inside and around the cockpit was too low. I
could not bend my knees up to get a good solid brace so it felt real
unstable. For this reason, I had to eliminate the Merlin LT from
consideration.

In my opinion, at 200 lbs., you're way too BIG for the Merlin LT.
