I bought a Polar Bird 3T after the ice went off here last year. For those of you that actually got to fish in you Polar Birds last season, do any of you have plans to spray the fabric material with 303 Fabric Guard or another product to make it more water repellent or does the material do an adequate job on its own? Also, are the ice anchors that came with it good quality/similar to Eskimos, or should I look to purchase a couple of sets of Eskimo anchors? Thanks!
