Narrow Spool Kit for Penn Reels

Alan, what the cost and advantages for me to convert to a narrow spool on my Penn Jigmaster 500?  Less weight, improved castability?

honestly?  you waste less line when you respool!!!!!!!!!  sorry, i couldn't resist...  

well, in theory, you could cast farther because there is less total spool mass and less rotational inertia to overcome.  personally, i like the fit and feel.  i think it's better balanced.  you will still need to fish 25# mono or better.  the tolerances between the spool and side plate rings is very sloppy.  i'm sure all of you have gotten 20# mono caught between the spool and side plate before.  on my narrow spool jigmaster, i fish 30#.  it never gets caught.  also, 30# mono will straighten out all of the lighter jig hooks.  you will loose less gear.  

personally, i think the narrow jigmaster is the single best reel for kayak fishing.  greased drags will be impervious to water.  you need only turn a sinlge screw to pop off the side plate.  there are no bearings to rust out.  the bushing are easy to clean and lube.  you have a nice power handle option.  please do not set the drags higher than 8 pounds.  that will round off the soft brass gear sleeve.  that's the only down side.  otherwise, it's a great reel.

Damn.... I guess spectra is out of the question for a narrow jigmaster  

I was hoping the narrow spool had tighter tolerences than the orginal.  

Is there no way to reduce the slop between the spool and side plates to prevent line suck?

for spectra and rockfish?  the calcutta 250.  very tight tolerances.
