hi, before i start i'd thought i'd mention i use a t3 and it don't stop me winning. ets will not make your birds any faster or slower, the buzz is actually getting a bird, clocking can be an anxious time for many(how many people have dropped a rubber or not put it in the thimble propely and it won't fit in the chamber) and the birds get to know this also, ets elminates this anxiety and makes the birds feel safe to enter the loft. also a lot of older pigeon fancier's struggle to get about so it helps in that position. it also takes away a lot of the paperwork at basketing night. i'm not totaly blinded by it though and i realise it could be upseting to some people when you have fancier's turning up with 30/40 birds clocked, and it can happen and will. this is the only problem i see. if you can't win without ets you won't win with it.
