Greg - Adhek poppers are in a different class in terms of their finish in comparison to the OKs. The OKs do look spectacular but believe me, you'll notice the paint gouging off within ten casts. Adheks, on the other hand are tough. The Goby I used with considerable success at Bugatti hardly had anything other little holes from the teeth after a few fish. They were incredibly resilient.
...... and if you were thinking of buying the OKs which I have seen as much as $60 locally, I paid $18 SING for them over there. Try about $15 AUD converted.
