I sort of teach the other way around and find when they have it good with the WP-18, then hand them the WP-20 and watch the smiles. But the flex hoses are nice for sure.
Just got my torch and rac in today, can't wait to hook it up. Been a little busy with house projects but I hope to squeeze in some time this weekend.
