Scott, you'll find the LB Airflo Delta's will
work VERY WELL on Bob's rods. The other one (I've got minimal time with this line; but looking forward to next weekend) is the new Hardy lines. Only 'grass cast' these lines, but was more than a bit impressed.
Back to your original question: I've got all my Meiz. rods lined with Airflo Deltas. Major difference is from 7 up, they're the long bellies, 6 and down the rod appears to prefer the shorter 'standard head.'
