Hi guys,
Nice of you to post that Jon. I recently built an 8-14lb 7' spin stick using the single foot K- series guides. I can say with absolute confidence that these guides (although terribly ugly) are the best single foot guides i have used, full stop. I run two different line weights over this rod 8lb and 15lb and can happily say i have not had one problem at all with line hangups.
In saying this it is definatley recommended that you use the corect tip guide to match or else you will still get tip wrap.
I have also looked at the double foot version, but am a bit scetical on how heavier rod you would be able to use these on. Am soon to build a new P.E 5 stick and am probably going to bite the bullet and put them on to see how they handle a heap of pressure.
Anyone who reads this is probly going to say "who are you? and where did you crawl out from" but after a few more people start using these guides i am absolutely sure that they will become extremely popular, especially amongst lighter line fishos.
Just my two cents. Dave.
