well, maybe it was unwise, but i just had some wheels built up for my first touring bike i am building. i got 700 x 23c because i figure i'll use the bike within the city as well as touring. would 23c make that much of a difference? when i have toured in the past i have pumped up the tires to a regular pressure like every other day. i will have front panniers. i don't forsee it hurting my hands.
