Just got a Johnny Morris ultra carbon combo bait caster only have used spinning reels before any tips on using it? 

 

Have you read any of the stickies yet on using a baitcast reel?

 

Don't cast hard.

Be smooth.

Use a weight from middle up for the rod's rating. (Aerodynamic lure doesn't hurt.)

Use a roll cast.

Set cast control (spool tension) to where the lure slowly drops with no over-run when it hits the water (ground).

Start with brakes high and work down.

Use something like 12-15 pound mono or co-polymer line.  (Many suggest braid, but it is a bit expensive.)

Sure I am missing more suggestions.
