Looking for a new iron club

I used Tourstage X-703 and just chaanged to Miura PP-9003 few weeks ago but I am not pleased with it. The feeling is not as good as X-703 and too much forgiveness (i think) so I cannot almost see any different between the bad or good shot. Even a good shot, I am not feel great on the impact.

Now I am looking for a new iron set, and have some shortlist:

(i) MP-59 (don't like it because it launched almost 2 years. I want a new model if possible);

(ii) Tourstage 709 MC (never try the demo yet. Don't sure if it much different from X-703);

(iii) Romaro Ray H (not sure if it too difficult for me);

(iv) Romaro Ray V (Never try the demo and don't like it pocket); or

(v) Miura CB-2007 (Never try the demo and concern that the feeling will be the same as PP-9003.)

My handicap is 9-10 and head speed is 105-110. If you have any recommendation or have other recommended iron, it would be great.

Many thanks
