if you look at the reels most of the reels in the combo kits you find for around that price have a way to shut off the clickers. I have a martin, there is a button on the back to slide down to turn it off, I have seen shakespeare and others have a small pinin the face of the reel, and I currenlty use pfluger reels and their reels, as in some shakespeare, you hit the reel spool release button, and pull out the spool, and you will find the "drag" clickers that are triangle shape, you just flip them so instead of the pointy side pointing towards the reel core, to pointing away and they will stop clicking, I like the clickers on though, I mainly use fly rods on crappie bluegill etc, so a drag is not important, in fact I hand strip line and fight the fish in front of the reel, the clicking is mainly just when you strip line or reel it up at the end of the day. also on occasion I have hooked into decent pike on small 12 to 14 size poppers, and then the drag and clickers help imensly, you would be amazed at how fast a 25 inch pike will mess your reel and flyline up if it runns to your reel, and then stops causing an overspin and creates a mess like in a bait caster, only problem is when the pike takes off again, the core of the flyline will actually cut the line sheath, and sheaths on successive coils beneath it, effectively forcing a respool, depending on the fly line you get it could get expensive if you do this 2-3 times in a summer. im me if you have questions on how I do it, or if you need more help picking out combos. I may not know it all, but I will try and help. as for panfish, I use several sizes depending on situation from 3wt to 8 wt. the 3 wt is a delicate tool and I often use it if you are in a mess of panfish especially crappies where there is not a full on bullnose run, on the other hand if I come across a lake with large mouths and pike that are more agressive than usual, I would tend to the higher sizes, and then switching to the 8wt to go for specifically for bass, but works good on pike to but is on the light side for everything over 30 inches or so. I always think that for starter fly fisher people the good standard is 6wt, the reason being is that there are greater options in lines and easier to find, often a float line with a wieght forward or rocket taper would be around $25 but for my 3 wt the same line would be around $45 just due to it is not used as much and not stocked as much, and they tend to figure you are fishing for trout at that point so you get into the more specialty lines. most kits you find will be in 5-8 wt. any will work, it is what feels comfortable in your hand and how uch spine you want, again depending on your target fish. I also find that a 5-6 wt is perfect for first time casters due to the weight of the fly line almost casts itself, it rolls the tippet over nice and easy with moderate tippet size. I find if you use 3 wt. the approach is much softer or the tippet will overoll and end up in a ball on the top of the water, where as on the heavy weight you will really have to push the rod and work to get your cast to roll, if it does not roll you will not get the distance or accuracy needed in usual fly fishing endevers.
hope this helps
