On the short end of the spectrum are our 5 foot Micro Tips. These 40 grain tips come in S2, S4, and S6, for Riffle, Run and Bucket. These tips are for true micro applications, rods under 9 feet long. That being said, we have used them with good results on 10 foot rods. But most users will find that these tips work best on 6 to 9 foot rods. These tips work best on rods from 2-weight to about a 6-weight, or about a 150 grain to a 225 grain Commando Head.
