Thanks for the suggestions on a swamped barrel, that confirms my decision on a swamped for my next build. The kit from TVM, however, is their "summer builder's special" and priced at $499 but it's for a straight barrel. It will be iron mounted which I intend to smooth and polish and leave in the white letting it naturally patina.
I'm very interested in building an Isaac Haines kit next, from either Jim Champers or from TOW which is now offering a stock pre-inlet for the swamped profile you choose. I'd like that rifle to have a Rice, swamped barrel and a higher grade of maple. I'm hesitant to spend upwards of $1,000 for my first kit though- mostly because I think a more expensive stock and barrel would just make me nervous while I'm learning.
I'm not opposed to going with a 36" straight profile though. It will have a Siler lock, which I think is a bit modern for the "Early Virginia" anyway, so who cares if the barrel is a bit short, too? ...Might make a nice hunting rifle once the metal looses it's shine.
One other thing this lower priced kit "offers" is a chance to put to use the James Turpin DVD's that I've been watching. He shows how to completely inlet for the lock, trigger, buttplate, etc. This TVM kit has only the barrel inlet and ramrod channel drilled.
