advice on jazz horns

so i currently play on a yamaha ysl-691, i love the horn, it’s a standard jazz horn, .508 bore, very similar to a king 3b. I recently found a listing for a getzen shoer deluxe that is a .500 bore. i’ve been wanting to go for a smaller bore horn, but i was wondering if it would be worth the trade, as i was thinking of selling my ysl-691 to fund the purchase of the super deluxe.
