A subwalk has a completely different action than a xrap.
A subwalk vs a xrap 10:
-subwalk glides 12 inches under water, a xrap jerks between 2-5 ft
-once you get used to a subwalk you can "glide" it anywhere. ( under docks, onto beds )
-a subwalk cast a mile, xrap's not as far
Dont get me wrong i like the xraps alot but i will use my subwalk over a xrap any day of the week. They produce easily 3-1 for me. I have subwalks in 6 colors and xraps in 9. I love them both but subwalks just workd better for me
