Advice about a new cue

[vmax4steve]

Okay, so here's the story - I used to play for quite some time with a Peradon Joe Davis 3/4 cue. I liked it because it was light and it was 59 inches which is great because I'm 6'3. Also it's made out of some very soft wood - it twisted whenever I did a more powerful shot. But it was not until I went to a local snooker coach to tell me that my cue is very curved. He said that snooker is a difficult enough game even if you play with a straight cue and that reaching any progress will be very hard with this cue.
So, I sold my cue to a friend and bought myself a new one - a Chinese 3/4 Omin cue. I didn't know a lot about Chinese cues but a lot of people recommended them so I thought they're worth a shot. The cue is just a little bit heavier, 58 inches but it's made of some very hard wood. It doesn't twitch at all even when I hit with a lot of power. I gave the coach a look at it and he said it's awesome - perfectly straight and he also said it has a nice balance so it's great. But the problem is that it's been 2 weeks since I bought it and I've been playing terribly ever since. Somehow my previous cue although crooked gave me a very good feel of the shot and I didn't need a lot of feathering - it all just came naturally. But with the new one I play very bad, it's like I've lost my touch - I try very hard and concentrate, try to keep my cue action as good as possible but at the end it doesn't happen. After 2 weeks of not being able to pot even the easiest balls I decided to try once more my old cue and play a frame with it - I started potting everything, and without thinking at all, it just felt right.
So I'm wondering how is this possible? Considering everyone's opinion that the new cue is better, I'm starting to think that maybe it's because I'm used to playing with a twisted cue that now that I have to create new habits of playing with a straight one. Has anyone ever came across this problem?

Hendry won seven world titles with a bent cue and Ken Doherty's is like a dogs hind leg.

Buy your old cue back, forget about getting it straightened and drop the coach who gave you such stupid advice.
