Here another view

I fish big rivers, I use T-14 (14 grains per foot) with dump bells (not all the time). Some places you need all that weight. In the summer time I still use T-14 not as much of it. My sink tips run 10 t. long (Ed Ward style) after useing Rio sink tip's for years Ed style is better! bar none!

Most of the guys I fish with change over to heavy sink-tip's and weight flys years ago.

Summer time I use both dry/sink-tips depend on the water temp. and water conditions.

You ask for a sink-tip secrets!
Never use a leader longer then 4 ft. if you use a leader longer then that your deffinting the purpose of sink-tip.

PS I use alot of tube flyies
