If he was in my kennels I'd both challenge and enthuse him with a series of long memory and ladder retrieves in heavy cover, give up on the "cued" blinds, and kick the white bucket into touch. Teaching blinds is a bit of an art rather than an exact science, but I've always tried to get over the cued stage asap; it really doesn't teach very much and if continued for too long can be counterproductive. Training with a some fresh shot birds as opposed to dummies or bumpers would be an aim too.
I hesitate to give advice as to collar training because I don't do it, but if you think I might be right about the confidence and boredom, throw the collar over the garden wall, put some fun and birds in his life, and avoid what to him is probably pointless repetition. To teach a genuine non cued blind, just stuff a dead bird into a bush (unseen) and send him from a few yards. You'll see the lights come on! Build it up from there.
