I'm getting ready to buy my first "high end" rod.  I've pretty much decided on a Kistler Magnesium.  The only thing I can't decide on is the power.  Im stuck between the MH and H.  Itll mostly be used for T-rigs, jigs, and maybe a c-rig every now and then.  Im leaning towards the MH, but would appreciate yalls opinion on which I should get.

I don't have that brand but do have a few rods.  My 7' MH rods are good for anything up to 1/2 oz be it jigs, spinnerbaits, tubes, etc.  When I hit 1/2 and over my H is all I use.  Think about your stuff and the way you fish and then decide.

I only own one heavy action rod, and honestly I don't even use it that much.  Unless you are constantly fishing areas with heavy, heavy cover then you should be fine with a MH.  I personally think the MH gives you more versatility as to which baits you can use with it.

The only "Heavy " rod I have is a flipping stick. Unless you are fishing realy heavy slop/cover or you are targeting big fish I think you should be OK with MH.

On the other hand, I don't know how well you gonna manage to T-rig and C-rig with the same rod !?

Most of my T-rigging happens using less than 1/4oz weight+soft plastic, I  C-rig only a few times a year, if at all..C-rigging requires about 3/4oz( sometimes 1oz)lead+ the rest of the stuff. There is a big difference. The MH rod will strugle with the light bait/lure and will strugle with the heavy stuff.

Generally, rods handle BEST the middle range the manufacturer's rating.

I chose my rods based on the weight of the lure/bait( mostly 1/4-1/2oz) and line I'll be using (10-15lb usualy)

PS:

I just pulled out my Cabelas catalog and I'm lookink at the Kistler Magnesium TS rod model MgSWMH70... I would laugh in anybody's face who woud tell me that a 7' rod rated MH/Fast, line 12-20lb will handle reasonably well 1/8 OZ !!! lure/bait. I think it's all a marketing "trick", nobody actually determined the real specs of this rod.

"Something is fishy in Danemark"

Hope I didn't confuse you more...

This will primarily used with T-rigs with 1/8 to 1/4 oz sinkers and 1/4 and 3/8 oz jigs.  With a C-rig thrown in there very rarely, probably with a light (1/2 oz or less) weight.

I have not had chance to fish a Kislter rod but I hear that they are an excellent rod manufacture.  

After reading what you're intending to use the rod for, I'd pick the G. Loomis BCR803.  As far as the power goes the MH should do.

Is this the rod you're looking at?
