I am giving serious consideration to using it this year. I'm after a quality freezer bait in various sizes, with shelf-life backup's, with a decent range of pop ups to match.
The source is competitively priced and I'm sure it will be available in lots of places, so easy to get hold of. My understanding is that it has quite a "meaty" flavour to it, probably no doubt the meaty marine pellet type favoured by DB.
To be honest, I like the whole range of DB baits - they are all quality products, and so I dont expect this to be any different. They've invested heavily in equipment to make this stuff, so they wouldnt skimp on the bait itself and risk it being a flop.
I wouldnt expect Terry Hearn to slavishly use this bait all year round. Lets face it, its just one product - other bait companies have lots, so whilst it might be quite possible for a mainline sponsored angler to fish exclusively mainline boilies (and I bet they may dabble with the green monster, chum mixer, and maize too), I dont think anyone would anticipate that "the source" is the right boilie for every situation, and neither would Terry.
