Makaira's and Penn VISX's are wonderful reels...
I happen to like Avets quite a bit too - I have over a dozen, and other than a pinion bearing or two encountered while pushing a JX a little too hard, they've been terrific reels...
A Pro30 (EX30) is a solid 100# reel - mine's filled with 80# solid, spliced to 130 hollow, with a topshot of 100# fluoro. An SDS50 (EX50) is a workhorse 130# reel - there's a reason you see many of them on extended long range cow trips...
I'd suggest a Pro30 - plenty of muscle for 200# class BFT. If you thought you'd also be pursuing cow YFT - on the 12+ day long range trips - and, you could only have one of the two reels, I'd suggest the 50 size.
