Not a huge difference at shorter lengths but at 14.5M+ there is a huge difference. If you're going to fish matches on commercials, where you'll be fishing the far bank far hours on end, you really are going to need a reasonably expensive pole. Fortunately for me, a good friend of mine is sponsored by Garbolino and so was always given their top of the range pole. When they brought out a new model, he'd sell me his old one (usually only a year or two old) at a good price.
Got a bit bored with that type of fishing after not too long though. When I get back to the UK, it's either matches on natural venues, or I might decide on a fresh start and take up fly fishing. Getting a bit old for lugging all my match gear miles along riverbanks and over fences/gates etc. Being able to park behind my peg was the best thing about fishing commercials.
