I have changed over to the 6lb nanofil. Absolutely LURV it!!! So easy to cast and is pretty robust. Just keep an eye on where braid meets the leader for fraying.
To answer your question SPOON,yes you can use the 10lb braid with a 4lb leader for bream, the only disadvantage is you may
lose a bit of distance on the cast with the slightly heavier braid. You may find it difficult to get a bit of distance especially
casting the sx40's (a good rod can also help with more distance) but plastics and slightly heavier HB's shouldnt be to difficult! If respooling is an option maybe look at braid around 6lb,this is a good middle ground between bream and flattys. You'd be surprised how much hurt you can put on a fish with 6lb line. I use 4 & 6lb braids for chasing everything from bream to larger school Jew in the river.
Depends what 10lb braid your using. You could be using 10lb fireline or 10lb castaway for example one is about 2-3 times thicker then the other. At the moment I am using Sunline Super PE in 8lb It is a nice soft braid that casts extremely well light enough for bream and heavy enough for most other species. I usually run a 6lb FC rock leader unless its quite clear and the fish are a bit spooky I will throw on a 4lb. In regards to leader length I usually run about a rod length but I don't let the knot go onto my spool as I find this can catch the braid and cause you troubles with windknots.
