Funnily enough I looked at what baits I could contemplate using, at this time, just yesterday. I'd had enough of catching carp, albeit the 'fun' type rather than the 'serious', and I just fancied catching a few roach...
Good quality casters/mags not always available in my area so I had a look in the store cupboard and found tares, hemp which, with the wheat (already frozen) and some soft bread for flake, punch etc I could offer a good variety. I also took expander pellets...
I'm NOT saying these baits would be good on all waters or when it gets REALLY cold, but today I caught a dozen average roach on a Stillwater, and this is the amazing bit, I had a fish or two on EACH of the aforementioned baits apart from pellet !
Flake and punch failed first thing, (7am) but came good later, tares caught a single roach almost immediately, as did wheat but did nothing after that, and hemp was the best....In fact I should have caught double the number but my strike was 'off it's best' - big time!
For the record the water is cooling now, but not cold, and although I had 7' of water in front of me all the fish were caught in less than 3'. Ambient temp around 8/10 degrees all day with heavy cold mist.
So, make of it what you will, but IMHO the above baits, along with caster and mags, could serve you well over the coming months if fishing for roach.....In fact a friend caught some decent roach on red maggot as well.
In addition,and I'm talking Stillwater carp here, I suggest meat in it's various forms can be good and sometimes even better if smothered with 'flavour' of one sort or another. Bovril usually good for my fishing.....
The key for me is patience and to give the baits every chance to work....I work on roughly an hour before changing and tend to bait various 'lines/areas' as Matchmen might do....Little and often though !!!
ps Going back tomorrow with a different float setup to suit shallow water fishing - that's the plan anyway !
