See my wiki entry from my Sig for assorted ramblings on knots. Personally I'd say you'll need to take the knot lower and deepen your knot hole but it's a bit hard to saynow hard that will be without seeing the handle. Order a knot and then set it with silicon and give it a go. From there you can see what needs to be done.
Both silver tip A and super have nice soft tips and don't forget loft will effect density.
