Strap for my New SBGA413

Hello can you share strap suggestions for the Shunbun, I am looking to get one which does not show the gap between the lugs and case after install. Prefer a flush fit. Cannot go OEM GS due to the price. I have seen Delugs, Tuns etc. About 3 weeks ago there was an asian store link someone posted and I cannot seem to find it(spent 3 hours looking for it). That had options to choose curved lugs and deployant clasp. I am a 6.75 wrist what size would you recommend 170 or 190? Please share your thoughts. Thanks.
