You had me till the 90 part. Truth be known 99 is even too generous and, for the few who could tell the difference and aren't lying about it, that difference still wouldn't add a single trout to the net. See Ive's post...the true difference in casting performance is a simple matter of 2 moving parts vs 4, and parafin will only solve part of it. I use the same 4 pc rod all year and never break it into more than 2. Only reason I own it is Rajeff doesn't offer the echo2 in a 2pc. I hate how often I have to "true it up" in a single outing. However, at the very least, a little parafin reduces the fly-away problem with the tip almost to zero.
Anyhow I don't see it as better vs worse. Just depends on your own habits and how you fish. And if you want a true pack rod go with 7 or 8 pcs. Otherwise...
If you don't need to hop a plane to fish, and you actually cast with it.....2pc. If you fish often in far away places, or you prefer to troll or stare at a bobber all day.....4pc. Oh, and if your rod never leaves the lake cabin, by all means.....1pc.
