The Tarpon 120 is a fine SOT...it would be a great day trip boat for the White...its pretty fast, tracks incredibly well, and its very stable...downside...small gear capacity, heavy, and hard to turn.
For overnights...I like a canoe....either a tandem or a solo...just depends on the conditions...High Water, Low Water, or lots of gear required. I solo the tandem...Its a drier ride at high water, and I drag less with the bigger boat at low...My solo is a Wenonah Vagabond...its a great flat water cruiser, but it takes in water occassionally when your run standing wave trains and almost every time you run a decent sized drop..Not the boat you want for extended Class II water, and forget class III...Same can be said for most SOT's.
If I was in the market for another solo...I'd be looking at the Wenonah Wilderness....bit bigger than my Vagabond. Cheers.
