This conversation seems to be about the appropriateness of stock 16-sized reels versus larger reels, for YFT over 200#. I got a killer deal (well under $400) on a Penn 16 VSX and sent it down to Cal Sheets last year, where they performed their machining magic to increase line capacity and drag (with a decent curve). Because I'm light-boned, not built like your typical fireman/linebacker long range angler, they also put in the lower low gear set (1:3 to 1). I asked Cal and Eric to install a BIG Tib handle, where the crank arm is at least a half inch longer than the stock Penn unit. My question for you experts is: Since modern bigger reels (30s, 50s) have, out of the box: 1) bigger drag capacity, 2) bigger line capacity, 3) lower low gears and 4) longer crank arms, why is this Penn 16 VSX, modified by Cal with specific intent on all of these 4 criteria, not a legit reel for cow tuna? I easily got 6oo yards of Jerry Brown hollow on it with plenty of room for long top shots, or the more fashionable short flouro or mono toppers. I wrapped a United Composites USA VIPER blank as a rail rod for this reel. Last year's November 10 day yielded plenty of great YFT, wahoo, and dodos for the freezer, but only 2 YFT over 100# came on board, so I didn't get a chance to test the reel, rod or myself on a +200# tuna yet.
Try an experiment with your reel, if you can. Get on a balcony and try to straight crank a solid 15# weight with you reel, then with a 50 if you have access, and see if you notice a difference.
I'm curious as to how much money you have invested in your reel with the upgrades. Also, how did he increase the line capacity?
