This is really a question for those who actualy know what they are talking about.
The benefits of an OPS are obvious. Light weight, added speed to shots, better feel, etc. The world of tapered shafts is nothing I have experience in. We all know what the stores say, but is it actualy true? If you have used an OPS and a Tapered shaft that were supposed to perform similarly (For example the Dolomites, and the SL and Synergy II) did they actualy both have the exact, or 99% same feel/performance? Should we all buy the hype?
Also on the sticks durability. For some one that is planning on buying an OPS and then when the blade breaks, putting a tapered blade into the OPS shaft, would you tell them to just go for the tapered shaft instead? If there was a corresponding OPS? Example again being the Dolomite, and SL/SynergyII. My thinking here is that since the blade is fused to the OPS shaft, you run more of a risk of damaging the shaft than if you were using a 2 piece combo.
It would be the same performance, if not then it's like 99.9% where you can't tell, but sorta depends on what blade you might stick in there too. Like you say, they are just a shaft and blade that is either fused or just have the joint painted over. Most sticks you can just heat and pull like a shaft blade combo so the risk of damage is minimal. Only time where you might damage it is by cutting the blade off, and you might need to chip out the remanants of the blade, but if your careful don't think it's a problem. But yes, getting a shaft blade combo over the OPS might be a little smarter.
