Starbuck
Like all things it depends on your abilities. Probably worth A tarmac trip dual just to see the differences. Like all things it depends on the person being trained. 8 hours just doing tarmac and cross winds sounds overkill to me. There is a huge amount of rubbish talked about tailwheel. Just do it, and have fun. lots of experienced instructors on the cub. At Waltham use JC, BH or a wider-body instructor!!
All the best
