For a less expensive option us a shooting head. Buy t15 in bulk & cut to size based on the rod wt.
Integrated lines/heads are easier ( although definitely not easy the 1st few times), but good ones are 4x the cost of a t15 shooting head.
Teeny also makes shorter head & markets it as freshwater sink tip. They are even weights: 200,300, etc. Shorter is better in some circumstances.
