Considering this Optima Alto F and was wondering would anyone know the length and I.D. of this whistle? Phil does not have any specs on his site. I own an Alto F bamboo flute by William Miller, has very good tone but it seems to take a lot of air. Looking to buy an F whistle with good clear tone. Thanks for any help.

Overall length is 19-5/8", length without headpiece is 15-7/8", ID is roughly (sorry no calipers) 3/4".

Thank you Peter for taking the time to give me some specs on that unit. That size will work perfectly for me. I sure do appreciate it. From the videos I have seen Phil sure can may that model sing. I have to keep reminding myself he is a professional player. How do you like yours?

I'm really impressed with it! I have had five of Phil's different whistles and the Optima is amazing in terms of playability and tone. It's definitely more of a free blower so be prepared with some lung volume for this and the low D Optima but it is a phenomenal instrument and holds its own again whistles twice or triple the cost. Also I wish more makers offered eased (scalloped? indented?) finger hole options. Especially for larger whistles it's nice to have that little bit of help with hole coverage, especially when you are starting out.

I am also thinking about the Kerry Optima Tunable Alto in F.
Either that or The Susato KildareLow F.
Both similar price, Anyone in a position to compare them against each other.

I have neither. But susato are known for having a very distinct sound so if you dont want that sound you dont want to go susato. A perk to the susato is if you like them you can buy bodies for the same headjoint and save some $ on a few other keys.
