hey bippo, bet your glad you put your trip back till May looking at the weather. I'm going to do a one night stay in wales in April to test out my tent & gear should realize what iv'e missed then, got similar set up to you with tank bag and soft panniers, tent across back only difference is i'll have my son on the back we're off to the TT in may just for long weekend, you'll have a fantastic time on Cornwall trip
wish i had the time to spare for a trip like that. i'll post some pics when i get back look forward to seeing yours
